PHOTOSCULPTU RE APPARATUS.

$PECIFIGATION forming part Of Letters Patent N0. 706,860, dated August 12, 1902.

' Application filed July 25, 1901. Serial No. 69,732. (No model.)

strasse, Berlin, in the Empire of Germany,

have invented new and useful Improvements in Photosculpture Apparatus, of which the following is a clear and exact specification.

My invention relates to an apparatus which differs from the apparatus of my applications, Serial No. 667,251, filed January 20, 1898, and Serial No. 32,033, filed October 4, 1900, in that the carriage for the lights and screen carries twosuch screens,which form an I5 angle together, so that no sectional planes between light and shade are produced on the model to be photographed, as is the case with the above-mentioned apparatus, but sectors formed by two sectional planes between light and shade are produced, which are photographed by the photographic or kinematographic apparatus, and consequently a series of pictures of these sectors formed by two sectional planes between light and shade are fixed on the sensitive film of the apparatus.

Furthermore, according to the present invention the apparatus whose carriage carries the two groups of lights corresponding to the two screens forming an angle together is so constructed that both reliefs and also busts of a model or a living person can be photographed by means of this one apparatus from a photographic or kinematographic apparatus, Wherefore means are provided for stop- 5 ping the rotatableplatform' or disk which carries the model or person to be reproduced, while the carriage carrying the lights and screens and moving in a straight line is actuated or left stationary and the platform or disk carrying the model or person is rotated.

Referring to the accompanying drawings, Figure 1 is a plan of the apparatus whose parts are in position for photographing reliefs; Fig. 2, a plan of the apparatus whose parts are in position for photographing busts Fig. 3, a side elevation of the carriage carrying the lights and screens as seen in the direction of the arrow in Fig. 1; Fig. 4, a middle section through the platform or disk carrying the model or person and through the operating mechanism on an'enlarged scale.

Figs. 5, 6, and 7 are a longitudinal section, a plan, and an end elevation, respectively, of a part of the operating mechanism for the carriage carrying the lights and screens.

In Figs. 1, 2, and 3 the carriage moving on rails 2 consists of a horizontal iron frame 1, which carries two bent supporting-frames 3, which are joined above and inclined toward the middle. The lights (electric lamps) 4, Fig. 3, are suspended'from these frames. The plate 7, Fig. 3, of a bar 6, moving vertically within a tube 5 and mounted at the upper junction of the two supporting-frames 3, constitutes the upper point of suspension of both screens 8, which consists of pivoted and adjustable links and are fixed below to horizontal adjustable frames 9.

A plate 10, Figs. 1, 2, 5, 6, and 7, is attached to the frame 1, and a nut 13, which is half open below, slidable on the end wall 11 of the plate 10, can be put in and out of engagement with the thread of a screw-shaft 14 by means of an eccentric lever 12. A quickeror slower driving motion is imparted to the said screw-shaft 14 from the shaft 16 by means of an ordinary intermediate gearing 15. This shaft 16 carries a bevel-wheel17, which in the same manner as a bevel-wheel 18 of a shaft 19, extending to the driving mechanism of the photographic or kinematographic apparatus, (not shown,) engages with the bevelwheel 20, Fig. 4. A toothed wheel 28, connected to the bevel-Wheel 20, engages with the toothed wheel 22 by means of the intermediate wheel 21, such toothed wheel 22 forming the hollow cone of a friction-clutch whose friction-cone 23 can be slightly raised or lowered by means of lever 24:, screw-shaft 25, and hand-wheel 26,Figs. 1, 2, and l, in order to put the friction-clutch 22 23 in and out of gear.

The shaft 27 of the friction-cone 23 is driven by means of toothed wheel 29 and toothed wheel 30, which latter is connected to the toothed wheel 31, that is actuated by a worm- Wheel 32, whose shaft 33, Figs. 1 and 2, carries a pulley 31 or the like, driven by a motor. (Not shown.) The toothed wheel 31 rotates on the fixed pivot 36 by means of a sleeve 35, such pivot being located in the central axis of a disk 37, which forms the rotatable platform for the model or person to be reproduced. This disk 37 rests upon an iron frame 38, which rotates freely around the hub of the toothed wheel 31 and carries a spring clamping-pawl 39, which can be firmly pressed, Fig. 4, against the edge of the toothed wheel 31 by a screw-spindle 40 by means of lever 41, Figs. 1 and 2. A slide-plate 42, Figs. 1 and 2, which is located on the side of the disk 37, shows a groove 43 and can be moved forward and backward by means of eccentric lever 44, so that the groove 43 of the slide-plate 42 secures, Fig. 1, or releases, Fig. 2, the end of the spindle 40 of the disk 37.

The apparatus operates as follows: When reliefs are to be photographed, the spindle 40 is screwed outwardly by means of the lever 41, Fig. 1, so that the spring clamping-pawl 39, Fig. 4, is lifted from the edge of the toothed wheel 31, and the slide-plate 42, Fig. 1, is moved forward by means of the eccentric lever 44, so that its groove secures the end of the spindle 40, and thus prevents the disk 37 from rotating. The disk 37 is then stationary, with the model or person located thereon, while the carriage 1 assumes the position of Fig. 1. If the driving-shaft 33 is now set in motion by the motor actuating the whole apparatus and the friction-cone 23, Fig. 4, is somewhat lowered-i. e., thrown into-gear by means of the hand-wheel 26, spindle 25, and leverrod 24 the shaft 33 rotates, by means of the worm-wheel 32, the toothed wheels 31 and 30, Fig. 4, and the latter rotates, by means of the toothed wheel 29, friction-cone 23, toothed wheels 22 and 21, the toothed wheel 28, and bevel-wheel 20. This drives both bevel-wheels 18 and 17, Fig. 1, and consequently the shaft 19, for the driving mechanism of the photographic or kinematographic apparatus and the shaft 16, which by means of intermediate gearing 15 rotates the screw-shaft 14, in whose thread the halfnut 13 of the plate 10 had been previously insorted by means of the eccentric lever 12. Consequently the carriage 1, fixed to the plate 10, and with it the lights 4 and screens 8, is moved along the rails 2 simultaneously and corresponding with the forward movement of the sensitive film caused by the driving mechanism of the photographic or kinematographic apparatus, so that as soon as the two sectional planes between light and shade, which are projected by the lights 4 past the rear edges of the screens 8, reach the model or the person situated in the middle of the disk 37 a series of sectors formed by the two sectional planes between light and shade are produced successively, according to the successive movement of the carriage 1, on the model or the person, the pictures of such sectors being fixed successively onto the sensitive film of the photographic or kinematographic apparatus. In order to photograph busts, the half-nut 13 is thrown out of gear withthe thread of the screw-shaft 14 by means of the lever 12, and the carriage 1 is moved into the position of Fig. 2, in which the axis of the bar 6 t'. 6., the point of intersection of the rear edges of the screens 8is located exactly above the middle of the disk 37. By screwing the spindle. 40 the clamping-pawl 39, Fig. 4, is pressed firmly against the edge of the toothed wheel 31 after the slide-plate 42, as shown in Fig. 2, has been previously moved back by means of the eccentric lever 44, so that the groove 43 releases the end of the spindle 40, and consequently no longer prevents the disk 37 from rotating on the axle 36. If the driving-shaft 33 is now set in motion by the motor and the frictioncone 23 is thrown into gear by means of the hand-wheel 26, spindle 25, and lever-rod 24, the carriage 1 remains stationary, because the same is disengaged from the screw-shaft 14 by means of the disengaged nut 13. The disk 37, which is taken along by the pawl 39 and toothed wheel 31, rotates, while the photographic or kinematographic apparatus is driven in the same way as when photographing reliefs from the toothed wheel 31 mediately by the bevel-gearing 20 18 and shaft 19, Fig. 1. During the rotation of the disk 37 and the model or person located thereon a series of sectors formed by two sectional planes between light and shade is likewise produced successively on the said model or person by the sectional planes between light and shade, which are projected by the lights 4 past the rear edges of the screens 8, the pictures of such sectors being fixed successively on the sensitive film of the photographic or kinematographic apparatus.
